Generally, the black shell shrimp can grow to a length of 2-3cm, a few individuals can grow to a length of slightly more than 3cm after adulthood, but basically no individuals can grow to 4cm. In the domestic environment, they can only grow to 2-3cm long.
Generally, the life span of the black shell shrimp is about 18 months, and a few individuals can live for nearly two years. If they breed more frequently, their life span will be shortened. If the environment changes suddenly, they may not be able to adapt and die early.
Generally, the black shell shrimp will have reproductive capacity only when it grows to more than 1.5 cm. After they have the ability to reproduce, they can be regarded as adult shrimps.
According to the different breeding environment and individual genes, the time needed for the black shell shrimp to grow into an adult is also different. Generally speaking, most individuals grow to adulthood in 2-3 months. But there are also some precocious individuals who can grow to adulthood in a suitable environment for a little more than a month.
After the female black shell shrimp becomes an adult, the ovarian development is completed, and it has the ability to hatch eggs. However, in the actual breeding, it is generally not possible to use adult shrimp as parent shrimp for breeding, and it is more recommended to use parent shrimp with body length of more than 2 cm for breeding. Because it can breed better quality shrimp larvae.
